HINGE.

Bpedcadon of Letters Patent.

Patented Merola-9, 1809.

Application filed November 4, 1907. Serial No. 400,589.

l ing section or sections in their open position interlock with the stationary hinge sections, and whereby the swinging member must be bodily raised to permit the Asame to be swung to its closed position.

The features of the invention are more fully set forth in the description of the accompanying drawing forming a part of this specification, in which Figure 1, is a plan view of my hinge in its Fig. 2, is an4 end elevation thereof. Fig. 3, is a sectional view, partly in elevation illustrating the hinge sections in their locked position. Fig. 4, is a plan View oi a set of hinges applied in position for use and likewise shown open. Fi 5, is a top plan view of one of the fixed hmge sections.

As shown, the hinge is preferably constructed for supporting the outside shutters of a window, and#- oi such form as :to enable the shutter to be readily removed.

ln Fig.- 4, it will he seen that the upper hinge is not provided with the releasing mechanism, the saine bein only shown applied to the lower hinge winch is sulicient for releasing the shutter ol ordinary size and weight from its locked open position. A ain, in the drawings I have shown the re .easing mechanism in connection with the stationary hinge section Which ier-preferable,

but it is obvious that similarl releasing mechanism could be provided upon the removable hinge section without changing the features of my invention.

1 represents the stationary hinge section forming the suppcrt for the movable hinge section attacheff to the door, which is suitably lined to the frame ofthe opening by screws or any other well known means. The free end of said stationary hinge section 1 is provided with a sleeve 2, the upper portion thereof being provided with the offset 3 forming a cut-away portion of one'- hali of the upper end of the sleeve, the lower r end projecting from the sleeve 2 being bifurcated to receive the releasing lever 4, which is eccentrically pivoted between the limbs 5. Lever 4 has'a circular upper end 10 and a weighted lower end 9.

6 represents the movable hinge section or leaf to which the shutter or moving element is fixed, the lower end is formed with a pro` jecting pintle 7, ad-f nted to iit within thesleeve 2 of the stationary section. The upper end of the hinge section is provided with a sleeve a, its edge-7, adapted to rest and ride upon the upper edge 7b of the sleeve 2. This sleeve a is likewise provided with an offset portion 8 corresponding with the offset 'portion of the stationary hinge section. Thus when the hinge is in its closed position the edge 7 a of sleeve a, will rest upon the upper edge 7b of the sleeve 2, riding thereon when it' is thrown open until the sleeve cornes to an alined position with the offset portion of the stationary hinge section, permitting the movable hinge section todrop, the sleeve portion a falling into the offset 3, of the sleeve 2, the upper wall of .the offset 8 rests upon the upper end of the sleeve portion 2, thereby forming 'a lock between the two sections, making it impossible with out breakage to move the shutter to its closed position without raising the inovahle hinge section. In this locked position the lower end of pintle 7, rests upon the inner eccentric portion of lever 4, in the position shown in Fig. l. lever 4 is moved outwardly, lifting the pintle 7 and raising the hingev section. 6 with its shutter a sulicient distance to hori To release the shutter, they zontally aline the sleeve corner 7c with the sleeve corner 7d of the sleeve 2, .releasing the interlock between the two hln e sections. In this outward position oi ever 4 the of the shutter acting upon the'eccentric l0 in serving to hold the lever in this outer posin tion. The operator now grasps the shutter and rides upon the upper edge oi sleeve 2.

removing the weight oi 'the shutter from lever 4, which having a weighted lever end 9,

intle 7 carrying the entire weight of. the s utter rests on thev outer curved surface v -at thev upper end of levere, the weight then automatically falls back into normal position. p 4

By this construction of hinge it will be seen that when the shutter is swun;a to its open position it will be automatically ocked, and itv can only be closed by operating tlie release lever.

I am aware that it is old to provide hinge sections with osets having inclined sh0ulders vwhich allow the movable memberto gradually fall into a lpartial interlock with the statlonary member. But this does not form .a sure lock, and a wind will readily `release the interlock and violently slam the shutter. v

With my device the walls of the two oil sets are vertically straight, so that a rectilineal interlock is formed which cannot be broken exce t by bodily raising the shutter a lvertica plane a sufficient vdistance to mechanically clear the abutting straight walls of the offsets. l

Having described my invention, l claim ,1. ln a shutter-lock, pivotally connected upper and lower sleeveseach having an oilset permitting the sleeves to interlock automatically at a selectedv point in their pivotal movement, and means for raising the upper sleeve 'for unlocking, the said upper sleeve being supported upon the lower sleeve lin unlocked position, substantiallyas described.

'2. In a shutter lock, piyotally connected upper and lower sleeves eachhaving an oilset, the projecting portion of the upper upper sleeve for position, and means for raising the 'upper sleeve for unlocking, substantially as de scribed.

3. In a shutter lock, an up er and lower Sleeve, eaehjhazing one-half o its periphery out away to form interlocking sections, a pintle carriedy by the upper sleeve pivotally engagingtlle lower sleeve,tlie upper sleeve projection in unlocked position swinging upon the lower sleeve projection, whereby the upper sleeve drol s automatically into an interlock witlrtlie ow'er sleeve when the projections and offsets are alined, and means engaging under the pintle for raisin the unlocking, substantia ly as described. i

4. In a shutter lock, an upper and a lower sleeve each having an offset, a pintlecarried ALBERT KRAUTH.
